The Ordinary disrupted the skincare industry by doing one simple thing: putting the active ingredient prominently on the label and pricing based on production cost, not marketing spend. But the brand's clinical format and overwhelming product range confuse as many people as they help. Here's everything you need to know.

What Makes The Ordinary Different

Most skincare brands sell you a benefit ("anti-aging," "brightening") in a proprietary formula you can't evaluate. The Ordinary sells you an ingredient at a specific concentration. This is both the brand's biggest strength and its steepest learning curve — you need to know which ingredients you need before you shop.

⚠️ Start With 2–3 Products Max: The Ordinary's range is overwhelming. Most people make the mistake of buying 8+ products and over-layering. Start with a cleanser, one treatment serum, and a moisturizer. Add more only after 4–6 weeks of assessment.

The Ordinary Products Worth Buying

01
🏆 Best Seller

Pros
  • Best-selling skincare product globally
  • Visible pore and oil improvements in 4 weeks
  • Works for every skin type
  • Extremely affordable
Cons
  • Can pill under some makeup
  • High concentration may cause initial purging
  • Some find zinc drying in high doses
Verdict: The entry point for The Ordinary. If you buy one product from the brand, it's this one — niacinamide 10% at $12 vs. $42 at Paula's Choice for near-identical efficacy.
02
💧 Best Hydration
The Ordinary Hyaluronic Acid 2% + B5
Triple molecular weight HA with vitamin B5 — comprehensive hydration serum

  • B5 supports barrier repair
  • Works for every skin type
  • Must apply to damp skin
Cons
  • Can feel sticky if over-applied
  • No treatment benefits beyond hydration
  • Apply to damp skin — draws moisture out if applied dry
Verdict: The essential step for any skin type. Apply to damp skin immediately after toning — the moisture gradient is what makes hyaluronic acid work.
03

Alpha arbutin for hyperpigmentation — the best value dark spot treatment available

The famous red peel — powerful weekly exfoliation at home
Pros
  • 30% AHA + 2% BHA is clinic-level exfoliation
  • Visibly smoother skin after one use
  • $10 for a powerful treatment
  • Cult product used globally
Cons
  • Not for beginners or sensitive skin
  • 10 minutes max — rinse immediately
  • Not safe if skin is compromised or barrier-damaged
Verdict: Used correctly (maximum 10 minutes, maximum once weekly), this is one of the most effective at-home chemical exfoliants available. Start once every two weeks.

The Ordinary Layering Guide

Layer products from thinnest to thickest. Water-based serums first, oil-based serums after. Never mix:

  • ❌ Vitamin C + Niacinamide in the same step (niacinamide reduces vitamin C's effectiveness at low pH)
  • ❌ Direct acids (AHA/BHA) + Peptides in the same step (low pH denatures peptides)
  • ❌ Retinoids + AHAs on the same night (too irritating)
  • ✅ Niacinamide + Hyaluronic Acid (different mechanisms, complement well)
  • ✅ Alpha Arbutin + Hyaluronic Acid (formulated together for a reason)

Starter Routine by Skin Type

For Acne-Prone Oily Skin:

Niacinamide 10% + Zinc (AM/PM) → Salicylic Acid 2% Anhydrous (PM, 3x/week) → Natural Moisturizing Factors

For Dry/Dehydrated Skin:

Hyaluronic Acid 2% + B5 (AM/PM) → Buffet (peptide serum, AM) → Retinol 0.2% in Squalane (PM, 3x/week) → Natural Moisturizing Factors

For Hyperpigmentation:

Vitamin C Suspension 23% (AM, alternate days) → Alpha Arbutin 2% + HA (PM) → Azelaic Acid 10% (PM) → Natural Moisturizing Factors

Frequently Asked Questions

Is The Ordinary actually good or just cheap?
The Ordinary makes genuinely excellent single-ingredient products. Their Niacinamide, Hyaluronic Acid, Glycolic Acid, and Alpha Arbutin are consistently top-ranked by dermatologists. The low price reflects minimal marketing and basic packaging — not formula quality. Where they struggle: highly unstable ingredients like L-ascorbic acid vitamin C, which requires sophisticated packaging to remain effective.
Can I use multiple The Ordinary products at once?
Yes, but selectively. The brand has a compatibility guide on their website that's worth reading. The most important rules: don't mix direct acids with peptides, don't use vitamin C and niacinamide in the same step, and limit yourself to one exfoliating product per routine.
Which The Ordinary products should beginners avoid?
Avoid the AHA 30% + BHA 2% Peeling Solution until you've been in skincare for 6+ months. Avoid the Vitamin C Suspension (gritty texture, can be irritating). Avoid layering more than 3 actives at once. The 100% Niacinamide powder requires careful mixing and isn't beginner-friendly.
